I am also interested in making government sourced data available, as it may be more current and accurate. I work in Canada and would be more than willing to help curate sources.

I am also interested in making government sourced data available, as it may be more current and accurate. I work in Canada and would be more than willing to help curate sources. What would be the best way to do this so the merged data set is the most accurate? Another source of logic would be to access the tax parcel cadastral data, which often times has both land,building values and sometimes size. So if the tax department thinks a parcel has a building, but there is no building in the main data set, then that parcel could be flagged for further analysis. Cheers James

No files, tests, or implementation entry points are named. Start by reading the linked discussion and examining how the merged data set currently handles source curation and validation. Done would require an agreed approach for incorporating Canadian government and tax parcel cadastral sources, including how discrepancies are flagged.
